About HLRN

Since 14.12.2012 the North-German Supercomputing Alliance (Norddeutscher Verbund zur Förderung des Hoch- und Höchstleistungsrechnens - HLRN) is a joint project of seven North-German states Berlin, Brandenburg, Bremen, Hamburg, Mecklenburg-Vorpommern, Niedersachsen and Schleswig-Holstein. The HLRN alliance, established in 2001, jointly operates a distributed supercomputer system hosted at Konrad-Zuse-Zentrum für Informationstechnik Berlin (ZIB) and at Leibniz University IT Service (RRZN) at Leibniz University Hannover.

In the past, six states have pooled their resources, along with funds from the federal government to purchase state-of-the-art systems , known as HLRN-I and HLRN-II. In autumn 2013, now seven states with funds from the federal government, have installed the HLRN-III system.

Berlin and Hannover are connected via the HLRN link, a dedicated connection for high performance data exchange.

HLRN is used by scientists from North-German universities and other scientific institutions of the seven states. It covers the huge demand for computing resources in the domains of environmental research, climate and ocean modelling, engineering applications like aerodynamics and ship building, as well as in fundamental research of physics, chemistry, and the life sciences.

Users and projects benefit from the support of a competence network of consultants which is spread over all participating institutions of the HLRN Alliance.
